When should my child transition from junior to adult bindings?

Transition when the child's calculated DIN exceeds the maximum of their youth binding (typically 4.5), when their boot sole length exceeds the youth binding's adjustment range, or when their weight and skiing intensity clearly exceed the youth binding's design parameters. This usually happens between ages 11 and 14, but it's based on size and ability, not age. If in doubt, have a certified technician evaluate whether the current binding is still appropriate.
